DEVICE. FOR REMOVINGPUTTY FROM WINDOW SASHES.

Application filed May 3, 1927. Serial no. 188,570.

This invention relates to an apparatus for removing putty from a window sash and analogous objects.

It is well-known that when putty used in glazing sash, doors'and thel'ike becomes set and firmly hardened it adheres closely to the wood so that when it becomes necessary to remove the putty as, for example, by reason of broken glass for replacement with new glass its removal by the usual method is extremely diflicult and slow and frequently results in splitting or otherwise mutilating the portions or" the wood to which it adheres in addition to irregularities in the removal of the putty and the main object of the present invention is to present a simple apparatus which may be easily and quickly clamped to the sash in such mannor that the putty may be removed from end to end of one side by one continuous stroke 01? a putty-removing tool with which the apparatus is provided thereby. avoiding mutilation of the sash and at the same time leaving the edge thereof adjacent the glass 5 smooth and regular for the reception of the replacement glass after the putty along each side of the glass has been removed by simllar operations. 2

In other words, I have sought to provide the clamping device with a guide capable o1 being adjusted to a position parallel with the line of cleavage for the putty and wood at any one side or edge'of the glass and to mount upon the guide a slide carrying a. cutting tool which is adapted to register with the line of cleavage so that the movement of the slide along the guide will cause the tool to remove the putty along the line of cleavage in substantially one operation.

Other objects and'uses relating to specific parts of the device will be brought'out in the following description.

In the drawings Figure 1 is a perspective View of a portion of the window sash showing my improved putty removing device operatively mounted thereon.

Figure 2 is an enlarged longitudinal vertical sectional View of the same device, part- 1y broken away, taken on line 2-2, Figing screw at one end is removed.

Figure 3 is a transverse vertical sectional view taken in the plane of line 33, Figure 2. I

Figure 4 is an enlarged detail sectional view of the guide: bar and adjacentcportion of its: supporting bracket together with the clamping screw for holding the guide bar 1n operative position.

As illustrated, this device comprises a clamping-bar 1 having at. one end an upstanding bracket 2' and its intermedi ate portion provided with opposite laterally pro ecting flat feet 3, the lower faces of which are disposed in substantially the.

are slidably and detachably mounted upon the bar *1- for relative movement toward and from each other and preferably extend upwardly therefrom for engaging opposite railsof the window sash as A'a-nd firmly holding said sash between them during the putty-removing operation.

For this purpose the lower ends of the heads -5 and -5 are provided with U- shaped saddles 6- adapted to ride along and upon the upper edge of the bar 1 with their opposite sides engaged with the corresponding sides ofthe bar to hold the 2 heads in an upright position during their longitudinal movement toward and from each other and also to permit the heads to beremoved by upward displacement when desired as, for example, when in storage or transportation.

These brackets are also provided with vertically spaced flanges 7 and -8 projecting inwardly from their adjacent sides toward each other for receiving the adjacent rails of the sash between them, the

sadd lies 6 being secured to the lower.

ends of the heads 5 by screws '9, Figure 2.

The upper ends of the heads 5 and -5 extend equal distances above the upper flanges 8 and also equal distances above the top portions of the saddles 6 and are provided at their upper ends with v similar lengthwise slots -10-- parallel with and equal distances from the upper walls of the slots in, the lower ends of the saddles --6- for receiving andsupporting a guide bar 11, the slots 10 being preferably open at the top to permit the removal of i said guide bar by upward displacement.

the tightening of the clamping heads upon the sash.

These clamping heads 5 and 5 i may be moved by hand lengthwise-of and upon the bar 1 to bring them into clamping engagement with opposite sides of the sash A and when properly positioned for tightening the clamping head -5 will be held against-outward movement by a follower block 12- which extends around the four sides of the rectangular bar 1 and is also slidable by hand lengthwise of and upon the same. A pawl18- is pivoted at 1l to the follower -12e to engage any one of the notches 4rand is yieldingly held in its holding position by means of a coiled spring 15 carried-by the block 12 just 7? above the pivot 14l asshown in Figure 2, said pawl being provided with a handle -13 by which it may be released against the action ofthe spring. a

An additional follower or block -46 extends around the four sides of the rectangular bar 1-, and is slidable lengtln, wise of and upon said bar by means of a screw 17 for adjusting the clamping head -5 toward and from the opposite clamping head --5- as the screw is rotated in one direction and for withdrawing the follower -16 from the clamping head -5 as the screw isrotated in the opposite directionto permit the clamping head 7-5"- to beimoved away from the clamping head 5. j j a a The inner end of the screw 16 is journaled in an opening in the upper end of the follower 16 and is held against axial movement by means of a screw 18 en gaging in an annular groove 19 in the adjacent portion of thescrew shaft as shown in Figure 2. it

The intermediate portion ofthe screw is engaged in a threaded aperture in the upper end of the bracket '2- which is secured to the adjacent end of the bar-1 by means I of a set screw or bolt -2l1-, the outer end plane of the ledges 7 and -8' toextend approximately the full length of the bar -1-.

Suitable means is provided for clamping and releasing the bar -11in and upon the upper ends of the clamping members -5, said means consisting, in this instance, of clamping screws -21- which are engagedin threaded apertures in one of the walls of theadjacent slots -10 as shown in Figure l. V

A tool carriage 22-is slidable by hand lengthwise of and upon the intermediate 3OTlJlOI1 of the guide bar 11 between the upper ends of the clamping members -'5 and 5 and for this purpose is provided with oppositely projecting handles 23.'

i This carriage is provided with a vertical putty asa of the sash A at its plane of cleavage with the sash.

-Tl1e-opening 2-=t and portion of the tool holder -25 movable therein are preferably rectangular in cross section to hold the tool-E26 in a plane parallel with the. guide bar 1l. c a

The upper end of the tool holder -25 is provided with a reduced cylindrical threaded extension -27 projecting some distance above the upper face of the carriage and engaged by a hand nut -28- having its lower end provided with an annular flange .-29+ which engages in a groove -30 in the adjacent portion of an upward extension 3l of the carriage 22" as shown in Figure 3 for holding the nut against axial movement and thus 'permitting the tool holder 25 with the tool thereonto be operatively adjusted vertically by rotation of the nut 28- in one direcj 7 tion or the other. i a

v Operation.

lV hen 'it is desired to remove the putty from any one side of the sash A- the clamping bar -Yl-will be placed in operative position 'upon a suitable supporting bench or table with its feet 3 resting movement after which the followers -16 thereon to hold the bar against turning a and clamping members-5 and -5 will i be drawn outwardly away from each other asutlicient distance toflallow the sash to be placed between said clamping members 5- and -5+ and upon thelower ledges 7 with the'line of cleavage between the putty to befremoved and the adjacent portion of the sash in exact alinement with the lower edge ofthecutter -26rr f This alinement can be accurately determined by first moving the cutter'to oneside of the sash and registering it with the line of cleavage of the adjacent portion of the putty and then moving the cutter to the opposite side of the sash to register it with the line of cleavage of that portion of the putty after which the sash may be tightly clamped by the adjustment of the followers 12 and 16- and screw -17 to firmly hold it bet-ween the clamping members and 5, it being understood that the guide bar 11 is then tightly clamped to the upper ends of the members 5 and -5.

As soon as the sash is properly adjusted and tightened between the clamping members 5- and -5 the tool holder will be adjusted by means of the nut 28 to cause the cutting edge of the knife -26 to enter between the putty and adjacent portion of the sash frame to approximately the plane of the glass as A whereupon the carriage -22- will be moved the entire length of the putty to be removed by means of the handles 28 thereby shearing the putty from the frame and at the same time assurin a smooth out parallel with the adjacent rail of the sash.

This movement of the carriage 2:2 along the bar 11 may be repeated if necessary but usually one movement from end to end of the sash rail will be sufficient to remove the entire line of putty.

The apparatus shown and described is particularly simple and affords an expeditious means for removing the putty without mutilating the sash rails but it is evident various changes may be made in the details without departing from the spirit of this invention.

li'hat- I claim is 1. A device for removing putty from win dow sash and the like comprising a guide adapted to extend along this putty line, means for holding the guide in fixed relation to the sash and a tool holder movable along the guide and provided with a putty removing tool.
